Superannuate is a verb that means to make or declare obsolete.

The Latin prefix S-U-P-E-R means ‘over,’ while annus (AH noose) — a word related to ‘annual’ — means ‘year.’ When someone is superannuated in a workplace, they are sent into retirement.

Being superannuated is something that can happen to an object as well as a person, for example: I can’t believe how much superannuated technology I was using in my old job at the printing press. Here we were in the mid-nineties using obsolete stuff like typewriters and fax machines like it was 1986.
